Definitions

  • the invention relates to a method for installing an axially low Oil scraper piston ring in a piston of an internal combustion engine, the Oil scraper piston ring has a curved resilient expansion ring, which, with itself in Corrugations extending axially, provided to support lamellar rings is and is open at one point and forms butt ends, which together in Pressure contact.
  • the invention has for its object to provide a method with which generic piston rings can be mounted safely and functionally without additional cost-intensive measures on the individual components are necessary.
  • the method according to the invention is based on the knowledge that multi-part oil scraper piston rings are handled separately during installation in the piston groove.
  • the expansion ring is inserted as a single part in the piston ring groove.
  • the butt ends are then aligned with each other and firmly connected.
  • a self-contained expansion ring is arranged in the annular groove of the piston, the links of which can no longer overlap. The connection is maintained throughout the life of the system while the piston is operating.
  • the invention is illustrated in the drawing using a schematic diagram and is explained in more detail below.
  • the invention is based on an oil scraper piston holder according to FIG. 1.
  • the oil scraper piston ring 1 has a very low axial height ( ⁇ 2 mm) and consists of an expansion ring 2 with corrugations 3 extending in the axial direction for supporting lamellar rings 4, 4 '.
  • the oil scraper piston ring is designed for use in pistons of internal combustion engines.
  • FIG. 2 shows an expansion ring 2 of the oil scraper piston ring 1 inserted in a groove 5 of a piston 9.
  • the butt ends 7, 7 'of the expansion ring are aligned with one another by means of a device 6 such that the butt ends 7, 7' lie against one another without overlapping.
  • the butt ends 7, 7 ' are then integrally connected by means of a suitable welding device 8.
  • the expansion ring 2 is now designed as a closed ring and can no longer fall out of the groove 5 of the piston 9.
  • the lamellar rings 4, 4 ' can be inserted into the groove 5 without the butt ends 7, 7' of the expansion ring 2 shifting as a result.
